Center Tom Colley was the fourth choice of the Minnesota North Stars in the 1973 Amateur Draft. Colley, who was born in Toronto, Ontario on August 21st, 1953, turned pro in 1973 with New Haven Nighthawks, where he would spend the next seven years.

Colley played just one NHL game during his career, and it came during his second pro season. He joined the North Stars in 1974 and was able to register a minor penalty in his brief time in the bigs.

After his seventh season with New Haven, Colley joined the Binghamton Whalers for the 1980-81 campaign before spending his final season as a player with the Collingwood Royals, an Ontario senior team.

Tom Colley stayed in the Collingwood area upon his retirement, coaching at the atom level. He then joined the coaching staff of the Collingwood Jr. 'A' Blues hockey club, serving as an assistant in two separate stints with the club.
